In addition the unloading rate took into account the nature of the vessel hull by the application of a “through ship efficiency factor”.</div> <bR> <bR> </tD> </tR> </TABLE></div> <bR> </td> </tr><tr> <td valign="top" colspan=2 height=32 BGCOLOR="#FFFBF0" TEXT="#080000"> <div> <A HREF="id54.htm" TARGET="_top" TITLE="Flooding in mid Wales"><U><B><IMG SRC="0111b180.jpg" border=0 width="27" height="24" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></U></A><B>  </B><A HREF="id51.htm" TARGET="_top" TITLE="prefeasibility"><U><B><IMG SRC="0121e160.jpg" border=0 width="30" height="22" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></U></A><B>  </B><A HREF="id2.htm" TARGET="_top" TITLE="SoftPort Introduction"><U><B><IMG SRC="0131b170.jpg" border=0 width="27" height="23" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></U></A><B>  </B><IMG BORDER="0" SRC="1x1.gif" HEIGHT="22" ALIGN="BOTTOM" HSPACE="0" VSPACE="0" WIDTH="27"></div> <bR> </td> </tr></table></body>
